AMBIQUAL: Towards a Quality Metric for Headphone Rendered Compressed Ambisonic Spatial Audio

Streaming spatial audio for immersive audio and virtual reality applications will require compression algorithms that maintain the localization accuracy and irrationality attributes of sound sources as well as a high-fidelity quality of experience. Models to evaluate quality will be important for media content streaming application such as YouTube as well as VR gaming and other immersive multimedia experiences.
